In this study, Nylon 6 is electrospun to produce ultra-fine nonwovens, and its characteristics as filter media are investigated. Electrospinning parameters including solution concentration, tip-to-collector distance, and the feed rate are changed in producing nonwovens in different fibre size distribution ranging from 50 to 150 nm in diameters. The solution concentration of 10 and 12 wt% produced the fibres with the average diameter of around 85 nm, where 15 wt% solution produced larger fibres with the average diameter of 121 nm. Finer fibres were able to process at longer tip-to-collector distance and at slower feed rate. The electrospun media that are processed at different spinning conditions are evaluated for its filtration efficiency and pressure drop. The electrospun nanofibre media shows the potential in application as HEPA and ULPA grade filter media, by comparing the filtering performance of nanoweb with the conventional melt-blown nonwoven media.}, number={9}, journal={MATERIALS & DESIGN}, author={Zhang, Shu and Shim, Woo Sub and Kim, Jooyoun}, year={2009}, month={Oct}, pages={3659–3666} } @article{hussain_khan_ali_parveen_shim_2009, title={Synthesis and Properties of Symmetrically Substituted 4,4 '-Bis(1,3,5-triazinyl)-Diamino Stilbene-2,2 '-Disulfonic Acid Derivatives as UV Absorbing and Fluorescent Whitening Agents}, volume={10}, ISSN={["1875-0052"]}, DOI={10.1007/s12221-009-0407-z}, number={4}, journal={FIBERS AND POLYMERS}, author={Hussain, Maqbool and Khan, Khalid Mohammed and Ali, Syed Ishrat and Parveen, Rasheeda and Shim, Woo Sub}, year={2009}, month={Aug}, pages={407–412} } @article{ahn_kim_shim_2009, title={Synthesis and application of o,o'-dihydroxyazo dyes and their metal complexes}, volume={10}, ISSN={["1875-0052"]}, DOI={10.1007/s12221-010-0643-2}, number={5}, journal={FIBERS AND POLYMERS}, author={Ahn, Sang Bum and Kim, Jae Pil and Shim, Woo Sub}, year={2009}, month={Oct}, pages={643–649} } @article{shim_koh_lee_kim_kim_2008, title={Evaluation of the dyeability of the new eco-friendly regenerated cellulose}, volume={9}, ISSN={["1875-0052"]}, DOI={10.1007/s12221-008-0025-1}, abstractNote={Three commercial dyes-direct, reactive, and vat dye-were applied to the new regenerated cellulose fiber which was prepared from cellulose acetate fiber through the hydrolysis of acetyl groups with an environmentally friendly manufacturing process.

They have composite crystalline structure constituted of cellulose II and cellulose IV.
